8125 because the inline candidate calls alloca or uses sjlj exceptions.
8126 (limits_allow_inlining): this new function to check if the inlining
8127 limits are satisfied. Throttle from currfn_max_inline_insns, not from
8128 MAX_INLINE_INSNS_SINGLE. The latter only makes sense if

8132 inlinable_function_p
